ronnie coleman probably would have kicked his a$$ when he was a young cop. here is a fight with kimbo vs gannon...a trained cop with a good chin.
gannon's widely considered a joke in mma, so when he spanked kimbo, his "street cred" was shot.
as for kimbo, he seems to have a surprinsgly good head on his shoulders. even in his old videos, he'd pop a guy's eye out of his socket, then help him out, give him a hug, shake his hand and call it a day.
as for kimbo in the ufc: he will get fucking murdered. he's just a little too old, a little too slow, and a little too unskilled. my prediction is dana won't have him fight anyone on the ultimate fighter til the ratings start dropping, then he'll get spanked. he'll get signed to the ufc, and have a stellar 0-4 career, then hang up his tapout shorts.
